What started as an epidemic mainly limited to Wuhan in China has now become a global pandemic in no time as declared by the World Health Organization(WHO). Now, there is more than 320,000+ positive cases with nearly 14,000+ deaths worldwide. As far as India is concerned, we have nearly 390+ positive cases with 7 deaths. While this is believed to have started in China in Dec 2019, the first case in India was reported back in late Jan. However, it got everyone's attention in early Mar with more number of cases reported everyday. Now, in just few days it has touched nearly ~400 with only 16000+ tests done so far. Now actions are being taken everywhere but is it too late to contain such pandemic which has made everyone to get scared worldwide? But to contain it further or avoid similar situations in the future, don't we need a centralized system to collect, analyze and alert before the magnitude of the situation is seen on the ground? While medical experts are busy in doing r...

With the entry of Cloud with a promise of reducing infrastructure cost, enhancing security by leveraging shared infrastructure, etc, organizations are slowly moving to Cloud to get the advantages of it. With multi-fold advantages, one big concern stays as-is - “Security”. Security in on-prem world is of multiple layers - Network Security, Infrastructure Security, and Application Security. However, in Cloud the security is of multiple layers but with multiple dynamic moving parts. Also, because of the nature of Cloud the regulatory bodies are strict on ensuring regulatory compliances and bringing in additional regulatory requirements.  There are multiple challenges in the cloud -  Slowly the penetration and the attack surface is changing, particularly in cloud environment. The various workloads have different needs - some are public facing in a public subnet and remaining are in private subnet with a strict firewall for inter subnet communication.  Ear...

In today's world, "information" is the key. With IT enabled world, we collect large amount of data from various sources but how effectively we can use such large amount of data is always a challenge. Different domains such as Financial, Sales, Security, Retail, Energy, etc. initiate and collect large amount of data from various source for their day-to-day IT operations and management. For e.g. in our day-to-day operation of using e-services, we perform various activities and transactions and one such example is e-banking. Do we ever realize when we do an online transaction how much data is collected to ensure safety of the transaction? Now, when each and every  online activity is monitored, extracting meaning out of billions of activities is a big challenge in IT enabled domains. When billions of transactions are happening per day, how do we find out which one of those is a suspicious activity. With the world becoming more and more IT enabled, IT security becomes extreme...

Wanted to share one error that I got while installing Microsoft Office Professional 2013 for which I had to spend almost 3 days to find the root cause. I also googled and found that many people have also faced the same issue but did not get if anyone had the solution. Sharing the solution that worked for me. Thanks to Dhaval Metrani, my colleague, who also helped me with this. If you get the following error in the log file (in the %temp% folder) while installing Office 2013 Failed to install product OSMMUI.msi ErrorCode: 1603  and the detail log shows ERROR: The network address is invalid then the same is because of Task Scheduler service is not enabled on the machine. 1603 is a generic error and some people have mentioned that the same could be related to deleting/renaming  %programdata% /Microsoft Help but the solution seemed to be related to Task Scheduler when the exact error was related to 'Network address invalid'. By default in Windows 7 and Windows Vista ...

If you get an error something like "Object Expected - Webresource.axd" while trying to run an ASP.NET application then please do the followings - 1. Many blogs suggest trying un-checking "check if File exists" in the handlers mappings section in IIS (IIS 5 or 6) and similar settings in IIS 7 but still sometimes it doesn't work. I did not found any websites suggesting the simple solution I found as I continued to face the same problem with the above solution. 2. The solution specific to my problem that worked was - check ASPNET has read/write access to the WebApplication folder. This is typically a problem in Windows Vista/7 where even an Administrator has some execution issues in the C drive too. So, it's better to move the WebApplication to drives other than C: like D:. Please check if this works. In my case it worked, hopefully it would work in your case too :-)

This is for the developers who must have been struggling with, why a Silverlight ComboBox is not working in a Windows Phone 7 application. Although the code does allow to put a ComboBox control to the page but actually it doesn't work when you try to run the page with ComboBox controls. This control has been removed in Windows Phone 7 development and you won't find this in ToolBox either in Visual Studio or Expression Blend. I think the ComboBox is not designed to work with touch screen input. Please check the msdn article on the same.

After a few months of break, I am back now and hope to post a few useful posts on Silverlight and Windows Phone 7 development in coming days. In between, the entire World, particularly the developer community, has now started talking about Windows Phone 7 (expected to get launched this Fall - Sep/Oct in India) after Microsoft's recent announcement on WP7 and release of development kit for the developers to start building Apps on WP7 before every common man :-) starts using it. Here, I will talk about how to start building your own application that can run on Windows Phone 7. People who are already familiar with Silverlight, would be very happy to see the same technology getting used for application development except few changes. I will talk about those changes in my future posts. The installations/applications that are required for WP7 app development are - 1. Visual Studio as IDE 2. Windows Phone 7 Development Kit (aka WP7 Developer Tools) Download Microsoft Visual Studio 2010 E...
